Sometimes, using a dietary supplement is necessary to make up for nutrients we can’t get from food sources alone. However, before fully subscribing to the use of any nootropic or supplement, you should figure out if that’s the right move for you. Here, we’ll be looking at what quercetin liquid drops are and if they have any substantial benefits.
In addition to consulting health care professionals to further inform your decisions, you need to gather as much information as you can about any substances you intend to start taking.
This goes beyond just reading drug labels.
To help you with this, we’ve done the necessary legwork on quercetin and all its properties. What’s more, we’ve found some of the best products with the right amount of quercetin for you!
What is Quercetin?
This substance is a natural pigment belonging to a particular group of plant compounds known as flavonoids. Some sources where this compound can be readily found include, but aren’t limited to, fruits, tea, grains, vegetables and certain types of wine.
The proper delivery of quercetin into the blood system has several benefits. Many of these have been confirmed by animal and human cell culture studies.
Before consulting a health professional on whether or not to add this substance to your diet, here are some advantages as well as adverse effects of quercetin you should be aware of.
Advantages of Quercetin Liquid and Capsule Supplementation
1. It May Limit the Onset of Inflammation
Quercetin’s antioxidant properties may help you limit the actions of free radicals in your blood and reduce inflammation.
What’s more, 500mg quercetin daily gummy intake in rheumatism patients was shown to relieve pain and increase ease of mobility.
2. It Mitigates Symptoms of Allergies
The ability of this substance to induce allergy relief has been well-documented. Animal studies indicate that this substance can give a certain amount of allergy immunity to users.
However, extensive studies of its anti-allergic properties have yet to be conducted on humans, and it’s unclear whether or not it has the same level of response in human cells.
3. It Can Lower Blood Pressure
Another possible benefit of a quercetin liquid drop addition to your diet is that it can help in blood pressure management. Rats introduced to measured doses of this substance showed improved blood circulation after it caused their blood vessels to relax.
A similar study in humans showed that 500 mg of quercetin resulted in a significant drop in blood pressure levels as well.
4. It Can Reduce the Risk of Chronic Brain Disorders
Quercetin can also prevent several degenerative brain disorders. However, it bears mentioning that the compound had no effect at all on middle-stage Alzheimer’s.
5. It Can Reduce the Effects of Aging
Activated quercetin has also been shown to prove quite effective against aging in some animal studies. Apart from eliminating aging cells, it also reduced several markers of aging.
However, more research needs to be done to understand this process.
Adverse Effects of Quercetin
For the most part, this dietary supplement is completely safe for consumption.
However, consuming more than 1,000 mg of quercetin in a day can cause tingling sensations, stomach aches, and headaches.
In addition to this, the interactions between quercetin and the body of pregnant and lactating women have not been properly studied. Because of this, you may want to stay away from the compound if you’re in either of these conditions.
